Cotinus coggygria Its lush purple color simply glows in the garden, and you’ll love the new look with each passing season! Loves heat, sun, wind and being exposed with the rest of your native plants. Growing to just 10 feet it makes the perfect accent between larger native oaks and pine. Royal Purple has the darkest foliage of its kind. Tiny flowers float above the leaves as a bekon to take a closer look. The flowers are so light and airy from a distance they look as though the plant has smoke rising up from within, thus its name. The longest blooming of all the ornamental trees.
